A 28-year-old woman presented with vaginal spotting and amenorrhrea for 7+5 weeks. Although a diagnosis of right cornual ectopic pregnancy by transvaginal ultrasound was made and a laparoscopic wedge resection of the left uterine cornus was performed, the β-human chorionic gonadotropin level remained high. Abdominal ultrasonography and computerized tomography of the abdomen demonstrated a 3.4×2.6 cm sized hypervascular cystic mass along the anterior aspect of the Inferior vena cava. A diagnosis of retroperitoneal abdominal pregnancy was made and a laparoscopic resection was performed. This is the first retroperitoneal abdominal pregnancy that has been treated through laparoscopy. © 2009 Lippincott Williams & Wilkins, Inc.
